摘要: Abstract The objective of this study was to investigate the kinetics biomass and determine influence temperature on distribution quality products slow pyrolysis. Coffee husk briquettes were produced by densification subsequently subjected pyrolysis at different final temperatures 623 K, 673 K 723 K a heating rate 0.5 °C/min. results TGA showed that coffee husks occurred mainly between 400 K 700 K. activation energy values ranged from 104.90 kJ/mol 345.2 kJ/mol for Friedman model 70.4 kJ/mol 288.8 kJ/mol FWO model. In composition bio-oil, higher temperatures, there greater production phenolic compounds nitrogen compounds. Lower promoted formation hydrocarbons acetic acid. content biochar did not differ with increasing temperature, but fixed carbon slightly 723 K. It concluded provided information pyrolysis, making it possible improve conversion process waste into products. Both isoconversional models effective in estimating Ea good accuracy. High producing bio-oil smaller amounts acidic compounds, is desirable use as fuels. addition, contains numerous chemical can be extracted used value-added
